The Schneider Electric ATV950U40N4 is a 4 kW class variable speed drive from the Altivar Process 950 series, designed for demanding industrial process applications requiring robust motor control, energy optimization, and advanced connectivity.
It is widely used in conveyors, crushers, mixers, extruders, pumps, HVAC systems, and wastewater treatment equipment, where continuous operation, stable torque, and system reliability are critical.
As part of Schneider Electric’s process-oriented drive platform, the ATV950U40N4 integrates monitoring, diagnostics, and industrial communication features that support digitalized production environments (IIoT / SCADA / process automation systems).
Its IP55-rated wall-mounted enclosure enables decentralized installation close to the motor, reducing cabinet requirements and improving overall system efficiency.
